Profiling of purified autophagic vesicle content and degradome in the maturing and aging brain - Part II


ABSTRACT: In this second part of the project “Profiling of purified autophagic vesicle content and degradome in the maturing and aging brain” four label-free proteomics studies were performed to characterize stabilization of potential autophagy targets upon lysosomal and/or autophagy inhibition.

Autophagy disorders prominently affect the brain, entailing neurodevelopmental and neurodegenerative phenotypes in adolescence or aging, respectively. Synaptic and behavioral deficits are largely recapitulated in mouse models with ablation of autophagy genes in brain cells. Yet, the nature and temporal dynamics of brain autophagic substrates remain insufficiently characterized. Here, we immunopurified LC3-positive autophagic vesicles (LC3-pAVs) from the mouse brain and proteomically profiled the  ...[more]
